Caution - Danger ahead!!!!!

You may call it your sixth sense or you may call it intuition, whatever you may call it.....have you ever felt in you r head about not doing a particular thing.....or you get to see what will happen if you do this(off course not the obvious ones)......may a times i have felt that by this action i might get into trouble or its not the right time to do certain things......have you ever got such kind of a forecast in your mind that really worked.....it could be anything....your friend coming over to your place after a long time,sudden snowfall,anything that you thought would happen and it did.....
Please share you experience......
